Test J: Type-0 Engine disconnected
[Based on: ADR 31/01, Appendix A, Annex 3, Clauses 1.4 to 1.4.2 inclusive.]
The following general conditions apply:
vehicles in Modification Category 16b shall be tested at 100km/h
vehicles in Modification Categories 17, 26 & 27 shall be tested at the lesser of 80% of
their maximum speed or 100 km/h
vehicles in all other modifications categories shall be tested at 80 km/h
the tests shall be done with the vehicle in the MLTM and LLTM conditions.
This test shall be done with Cold Brakes. The average temperature of the service Brakes on
the hottest Axle of the vehicle, measured inside the brake linings or on the braking path of
the disc or drum, must be between 65 ºC and 100 ºC prior to any brake application.
The test must be conducted in the following conditions:
the vehicle shall be in the MLTM condition, the distribution of its mass among the Axles
being that stated by the Manufacturer; where provision is made for several arrangements
of the load on the Axles the distribution of the maximum mass among the Axles shall be
such that the mass on each Axle is proportional to the maximum permissible mass for
each Axle
every test shall be repeated on the vehicle in the LLTM condition; there may be, in
addition to the driver, a second person on the front seat who is responsible for noting the
results of the test
the limits prescribed for minimum performance, both for tests with the vehicle in the LLTM
condition and for tests with the vehicle in the MLTM condition, shall be those laid down
hereunder; the vehicle must satisfy both the prescribed stopping distance and the
prescribed mean fully developed deceleration, but it may not be necessary to actually
measure both parameters
unless otherwise specified each test may comprise up to six stops including any needed
for familiarization.
For a vehicle to pass the test, the stopping distance must be within (0.1v + 0.0060v
2
) metres,
where v = the test speed in km/h, with a mean fully developed deceleration of at least
6.43 m/s
2
, and the braking force between 65 N and 500 N.
Note: For vehicle tested at 80km/h and 100km/h, the stopping distances must be within 46.4m and
70m respectively.
